PHYSIOLOGY XA FRAMEWORK 1

Basic unit of matter: [blank_start]atom[blank_end]

Atoms bound together: [blank_start]molecules[blank_end]

Basic unit of life: [blank_start]cells[blank_end]

Multiple cells = [blank_start]tissues[blank_end]

Multiple tissues = [blank_start]organs[blank_end]

Multiple organs= [blank_start]organ systems[blank_end]

Homeostasis is the process of maintaining a [blank_start]relatively stable[blank_end] enviroment

The law of mass balance is for a substance to remain constant in the body, any [blank_start]gain[blank_end] must be offset by an [blank_start]equal loss[blank_end]

Local control is restricted to a [blank_start]tissue[blank_end]

During [blank_start]local control[blank_end] the cells in the vicinity are the ones to inciate a response

[blank_start]Reflex-Long distance[blank_end] control is a systematic response in the body

Reflex-Long Distance control typically uses the [blank_start]endocrine[blank_end] and [blank_start]nervous[blank_end] systems

Negative feedback [blank_start]counteracts[blank_end] stimulus

Positive feedback [blank_start]reinforces[blank_end] stimulus
